The Humble Bundle releases have become quite an event in the world of indie gaming, and the recent Humble Introversion Bundle is certainly no exception. With six days until its completion, the Bundle has already sold over 150,000 copies, earning the developers and the supported charities over $630,000.

This edition of the Humble Bundle includes Darwinia, Multiwinia, DEFCON and Uplink, Introversion’s entire catalog, for any donation at all, but as always, there is an incentive to give more. Beating the average purchase will net buyers three more titles: Aquaria, Crayon Physics Deluxe, and the recently added Dungeons of Dredmor.

Keeping this package fresh so close on the heels of the Humble Voxatron Debut are two prototype tech demos, along with the source code to the four main games from the Bundle. Modders are now free to have their way with each of Introversion’s four releases, or as the developer’s suggest, “check out what an award-winning game looks like underneath all those pretty bitmaps, vectors, and textures!”

Keep in mind that every donated penny’s destination can be delegated by the buyer, but thankfully the folks at Humble Bundle provide a default split between the developer(s), the charities, and the Humble Bundle company itself for the indecisive among us.

These developer-specific Humble Bundles might only be asides to the main Humble Indie Bundle releases, but it’s great to see a group of deserving games from a consistently terrific developer getting their time in the spotlight, regardless of their age.

This is the seventh release from the Humble Bundle team, following the Voxatron Debut’s release by less than a month. In fact, this is the fourth Bundle in as many months. Between these consistent releases, the promise of Humble Indie Bundle #4 coming soon, and the brand new Indie Royale delivering its deals every two weeks, gamers may need to start clearing some space on their hard drives to make room for the quickly approaching flood of indie games.
